New here, Tormek Refurbish how to?

[SharpenADullWitt]

In mid, 2010, I purchased a Tormek from a local man, who didn't like it.  He was given it by a friend who died from cancer, after helping him clear out his shop, so his wife didn't have to.  Lack of practice and the reminder of his friend was why he sold it, and I was lucky enough to find it on CL for a good deal.
Last year, I was finally ready to start learning when an emergency at work, drove up my hours (70 hours a week for several months).  Spring hit and I moved outside (house projects), and now winter is just about here and I am straightening up the shop and going to learn.
I ordered the jigs I didn't have, as the late fellow that had this was a turner (I have no lathe yet).  I wanted one for years, but couldn't justify it and just took a lot of time to refurb used plane blades.

Being this has sat this long, I went through 30+ pages and didn't really see a write up about refurbishing these.  I saw bits and pieces.
The prior owner had the stone rust on the shaft.  He chipped it getting it off and bought a replacement.  Since the shaft had rust, I removed it, and now my father has (already worked the chip out), the old stone, shaft and water trough.  (planned project, a treadle version)
Does one replace the bushings, automatically, when they install the new shaft?  (I know I should lube either, and the old shafts were taught to lightly lube, I am guessing the stainless do not need lube)
What else to look at on the underside? (need to record the model number so I can download the newer manual)
I tend to see lazy susan's at garage sales, so plan on going that method for it.  (wondering if others have done it, as I am wondering about drilling a stop bolt hole in one)

Headed out to work, so may be more later (still have to read the last of the forum pages),
Thanks all.

Even the new stainless steel main shaft needs to be lubricated where it rides on the nylon bearings.

Randal,
   Did you make the treadle machine? Previously I posted a link to treadle grinder a fellow uses to sharpen knives.

   The following link gives a description of his grinder set-up.

   I am curious to know if you pursued your idea.

I wish.  He came up with another use for the treadle he has, a commercial sewing machine he uses with leatherwork (handicapped friend he does work for, bought it for him).
He ended up using the Tormek stone and several other bits (my duplicate jigs), on a copycat machine (since he is up in age, as well as several of his woodcarving buddies, they figure used is a more cost effective solution for the amount of use they will get). while looking for a used deal.

At the risk of sounding like a T4 salesman, I think the T4 would be the ideal machine for a group of older woodcarving buddies. Even if they should to"build their own" (fine with me), having the new T4 as an option lowers the realistic cost of used equipment.

The T4 wasn't out when we did that.  He has used hand wheel grinders for years, and always talked about the large treadle wheel grinder his grandfather had.  I had even offered to leave my 2000 over there, but he was afraid he would end up using up the stone. 
I agree that the T4 should be looked at, but now he will wait until my old stone is no longer usable.
One benefit, IMHO about the treadle idea over the others, is exercise.
